tion as is the case where the button'is pier'ce'd' before attachment..

lith this piercing staple I employ an imperforate (not apertured for the staple) 'snap fastener' member 30 which is ,cup-

shaped and provided at the bottomof the cupped portion with an annular positioning groove 3l for receiving the points of the stapleshanks.` The fastener member 30'is formed ofvsheet metal and the` groove is formed 'by crimping the metal, a rib 32 being 'pushed out on the opposite side of the sheetv at the operation producing the groove.- The snap fastener member may be of Vany suitable typeor may be either'male or female. Herein a female member of ythe type having a spring ring 33 is shown. In" anytype or variety the cupped portion is left open.

In Figure 3 are shown the burrs or jagged edges of metal formed when the staplel pierces the fastener member. These burrs lif left are likely to obstruct the proper mating of the snap fastener parts, would catch and retain dirt, grease or other material rendering the article unsanitary, would possibly injure the fingers of the user, and would be so unsightly as' to create an unfavorable impression.

Herein I have shown a setting pin or die 40 for turning both the prongs ofthe staples and the burrs which they formV inthe fastener. members. `This setting pin must be of relatively small diameter for it must enter the open cupped portion of the fastener members to reach the staples.` Heretofore so far as I am aware no setting die hasbeen produced or designed capableV of entering this limited opening and at the same time turning the bui-rs about the staple shanks.

This pin has a pair of grooves 4l sloping toward the center of their length and also sloping toward a'partition wall 42.. The grooves are suiiiciently long and deep as shown in Figure l to accommodate all of the bent portion'of thestaple Shanks. The edges of `the grooves are thus allowed to reach the burrs to turn them. To assist iii turning the burrs, the. outer edge of the pin is flattened as shown at 43 inf` ig. 5.v The grooves 41 also arekmade somewhat wide-r at the center than is required forthe diameter of the staple Shanks and the inwardly sloping portions of the grooves at these be apparent that changes may be made within the spirit ofthe invention asset forth in the appended claims.v I claim as my invention:

' 1..A:fastener assemblyV comprising afas.- .tener membergand a headed attachingmem-- ber piercing apiece of goods and said `fastener member and deformed behind the fastener member to secure the same on the goo'dsgV said'attaching member including a.

pointed shank portion, ahead Tand a--cover aiixed to said head, saidcover including a sheet of material crimped lintermediate its rim and center t'oiform a socket forthe head ing an element including a deformable shank and head anda .cover for said head including a sheet of material crimped intermediate its rim and center to form an annular rib turned inward beneath said head, and a lateral flange at therim, and ya second sheet of material secured upon said crimped sheet and closely overlying the same above said head to form a smoothneat and substantial structure not easily ybent by driving upon the head. x

3. A fastener attaching member comprising a rivet having a piercing pointed shank.

and head and a cover for said'head having sufficient strength and rigidity to force the rivet through sheet metal material without crushing the cover, said cover includingla sheet of metal crimped between its rim and center to forma rib bent beneathv said head to secure the cover thereon, the rim of said sheet and tlie'lowersurface of said rib after bending lying substantially in the same plane and said rivet-deformed .when in its attached position. l

4. The device set forth inclaim 3 which further includes in "combination la second and relatively smooth sheet of metal attached to said crimped sheet so as to closely overlieth'esame toy provide av smooth solid cover.

5- A11 irttlhrvigg. memberffor fasteners" izo walls of the chamber crimped under the v. head of the piercing member, said cap also comprising a crown and having its periphy ery crimped about the periphery of the disk.

Y `6. An' attaching member -for fasteners comprising a riveting member,said rivetingl member comprising a headed staple, a cap comprising a disk having a chamber, the lower walls of which are crimped beneath the head of the staple to tightly hold thev same, and a crown for the disk having its peripheral edge crimped about the peripheral edge of the disk.v v 7. A cap disc for headed devices formed from a sheet of metalcomprising a downwardly extending peripheral rim portion, inwardly sloping side walls, upwardly positioned center walls and an integral cover, `and said cap disc when in its linal position having the merging lportion ofthe inwardly sloping side walls and the upwardly positioned center walls extending -inwardlyto Vform a locking flange. i 'i Y Y 8. A cap disk adapted to enclose the head of a piercing member, sai'cl cap kdisk com-Y prising a peripheral downwardly? extending y rim portion, an inwardly extending sloping side wall connected therewith, a central vertical wall merging with the lower edge oi v l said inwardly extending side wall, and the sloping wall and the vertical wall, where they merge, being bent inwardly-to form ay flat rim to underlie the head ofthe piercing member. f 9. A cap disc adapted to tightly grip a head of a staple, said disc being formed into a small hollow chamber with inwardly projecting lower walls, said walls then extending outwardly, upwardly and down- 4@ wardly, and a cover crimped about the outer edges of said cap disc. c In testimony whereof, I have signed my name to this specification this 14th day of January, 1929.
